You think the puppy is about to get the Guard Dog class? :) I would say Werewolf, but the librarian put too much import on his being concerned about his friend.
Interesting way to reveal hidden class/jobs :D Players dont Even know if they clear the conditions till they find the item. makes you wonder what conditions Melting Snow met to get the quest started? Puppy dog eye attack lol (≧∀≦)
